ADJUSTMENT FOR WOODWORKING MACHINES.

Application filed September 18, 1920. Serial 110. 411,252.

To all whom it may concern:

Be it known that I, FRANKLIN L. LANE, a citizen of the United States, residing at Beloit, Wisconsin, have invented certain 6 new and useful Improvements in Adjustments for Woodworking Machines, of which the following is a specification.

This invention relates to wood working machinery, and especially to wood planing 1 or matching machines into which boards are automatically fed in constant succession.

The invention consists in an improved automatic sizer thatis to say, in the machanism whereby the distance between the cutter heads is adjusted to fit the width or thickness of the boards being feed thereto. Heretofore two levers have been provided at the operators station at the rear end of the feeding table, one for adjusting the position of the live corrugated feed roll as the horizontal dimension of the stock on the feed table changes, and another for correspondingly adjusting the position of the side cutter head. The present improvement provides for the accomplishment of both these adjustments by a single lever, whereby greater accuracy and simplicity of operation are attained. It also provides for means for locking the cutter head (and consequently the feed roll also) in any of several adjusted positions corresponding to standard widths of lumber, and for means for making fine adjustments of the roll and cutter head from time to time, as the cutters wear or in setting up the machine. 7, I In the accompanying drawings I have shown only so much of the planing or matching machine and of the automatic feed table as is necessary to illustrate my invention and its application to said machine and table. Figure 1 is a side elevation of the rear end of the feed table and front end of the planing or matching machine.

Figure 2 is a plan view of the same. Figure 3 is an end view looking towards the left in Figures 1 and 2 at a point just to the rear of the screw feed roll.

Figure 4 is a cross-section on line 4-4 of v Figure 2, and 50 Figure 5 is a cross-section on line 55 of Figure 2. 1 In these views, 1 representsthe planing or matching machine frame, 2' the frame of the feed table and 3 the bed connectin the same. 4 and 5 represent cutter heads 0% the planing or matching machine and 6 and 7 the vertical feed rolls of the feed table, roll 6 being corrugated and positively driven, as usual; 8 represents the last of a series of screw rolls of the feed table, which feed the stock forwardly against the inclined end guide 9, and laterally against the side guide 10. ,The cutter head 4 and the feed roll 6 are laterally adjustable, as usual, to accommodate stock of different horizontal dimensions, but, instead of being separately and independently adjusted, as has heretofore been customary, they are, by the mechanism of the present invention, simultaneously adjusted by the manipulation of asingle lever. g

This lever, shown at 11, is provided with the usual spring latch 12 and ratchet segment 13, adjustably mounted on standard 35, as shown in Figure 3, and is keyed to the shaft 14 extending rearwardly along the side of the machine. An arm 15, also fast on said shaft 14, is connected by a link 16 with a bracket 17 slidable on a guide rod 18 and connected to the cross-head 19 by ascrew rod 20. Cross-head 19 is slidable on the guide rods 21 and 22 (see Figure 3), and carries the corrugated feed-r0116. The purpose of the screw rod '20 is to enable fine adjustments of the roll 6 to be made. Rod 20 is provided with a handle 24 by which it is rotated for the fine adjustments. 23 represents a belt shifter or other control lever.

At its rear end the shaft 14 is journaled in a standard 25 and has keyed to it a forked arm' 26, connected by wa pair of links 27 with a collar'28 fast on a sleeve 29, slidable in an opening in the frame 1 and having ratchet teeth 30 cut in its lower side. Through the sleeve 29 passes a rod 31,rotatable in said sleeve but prevented from sliding therein by a collar 32 and nuts 33, and threaded at both ends, on its outer end for the reception of said'nuts' and on its inner end to engage a threaded opening in the side head 4; as will be obvious, the screw rod 31 is for the purpose of making the fine adjustments of the cutter head.

The teeth 30 are spaced apart to correspond to standard dimensions of stock and are engaged by a pawl 34, pivoted on the frame and connected by a. link 36 to an arm 37, fast on a shaft 38, j ournaled in the standv cured to it in the vicinity eithe hand lever 11. 1

An adjustment of the cutter head 5 is provided for, as shown in Figure 5, by

which engages a roller on a pin 4 2, adjustably mounted on the -frame. It will be evident that when lever 11 is actuated to move roller 6 towards or away from rollZ, guide 9 will be moved with it and that the angle of the stock face of said guide becomes steeper as the distance between said rolls increases. vAt the same time as the roll 6' and guide 9 are adjusted, the cutter head 4 is adjusted, the 'pawl 34 being first disen: gaged by the pedal 9 and connections. Both cutter head and feed roll and guide are locked in adjusted positionaby said pawl,

and the spacing of the ratchet teeth 30 en ables the operator'to make his adjustments correspond with standard widths of the stock. l v v The cutter heads and rolls being set for a given width of stock, when the incoming stock changes in width, say from seven and a half inches to nineand a half inches, the operator steps on the pedal to unlatch the pawl, starts to pull on the lever 11, releases the pedal and pulls leverll further until the pawl engages the next tooth 30. The sleeve 29 is interchangeable to suit various sizes of stock being fed. The usual top.

rolls andother feed rolls on the bed 3, between the feed rolls 6 and 7 and the cutter heads 4. and 5, are not shown in the drawing, 43 in Figure 4 represents a cylindri cal guide'for the cutter heads and 44 in Figures 1 and 4 a'guideway for the lower parts of saidheads. .7
